Question

-2/5-[-17/15-(2+7/10)]-5/4

Answer 1

Resposta:

191/60

Explicação passo-a-passo:

$-\frac{2}{5}-[-\frac{17}{15}-(2+\frac{17}{10})]-\frac{5}{4} \\ -\frac{2}{5}-[-\frac{17}{15} - \frac{37}{10}]-\frac{5}{4} \\ -\frac{2}{5}-[-\frac{29}{6}]-\frac{5}{4} \\ -\frac{2}{5} + \frac{29}{6} - \frac{5}{4} \\ \frac{133}{30} - \frac{5}{4} \\ \boxed{ \frac{191}{60} \approx \: 3.183}$
